Yup. I bought the OG Switch for Breath of the Wild. Literally for that one game. Those big platform exclusives absolutely are system sellers and Nintendo are fully aware of the fact.
I do hate that as a strategy, because we don't live in a world any longer where platform exclusives should exist. All hardware is homogenous, and any platform locking is completely arbitrary.
We hope Nintendo will take this as a lesson to ditch platform exclusivity, but I'd bet anything they will draw the exact opposite conclusion and double down.
I won't be surprised if the next gen of Nintendo gaming is always-on streaming powered by cloud GPUs.
